4. Say if the following is true or false: a. \( 4+5=5-4 \) b. \( 7-2=2-7 \) c. \( 4+(3+2)=4+(3-1) \)

The first expression, \( 4+5=5-4 \), is false since \( 4+5=9 \) and \( 5-4=1 \). The second expression, \( 7-2=2-7 \), is also false because \( 7-2=5 \) while \( 2-7=-5 \). For the last one, \( 4+(3+2)=4+(3-1) \) is also false, as \( 4+(3+2)=9 \) and \( 4+(3-1)=6 \). So, all three statements are false! Engaging with numbers can sometimes feel like playing a game where you need to watch out for sneaky traps! When evaluating equations, remember to do the operations from left to right for addition and subtraction. It’s like following steps in a dance – if you miss a beat, you might end up with the wrong steps! For a little brain workout, think about how these statements would change if we used multiplication or division instead. Try creating your own equations and see if they hold true. It’s a fun way to engage with math, and who knows, you might stumble upon a hidden pattern or two!
